Mental Health Services Utilization by the Population That Suffered Water Supply Interruption Following Mariana Dam Failure (Brazil).

OBJECTIVE: Disasters may have major impacts to mental health and to the utilization of mental health services (MHS). Moreover, these effects may be worsened by the preclusion of access to basic services following the event. The aim of this study is to evaluate the utilization of public MHS by the population that suffered water supply interruption following the Mariana Dam Failure in Brazil, 2015. METHODS: We conducted an Interrupted Time Series analyzing secondary health data from the municipalities that faced water supply interruption, comparing it to data from the other municipalities of Minas Gerais state. RESULTS: We found a higher immediate (RR: 1.78; 95% CI: 1.25-2.53) and gradual (RR: 1.05; 95% CI: 1.03-1.06) change in the rate of mental health visits (MHV) in the affected population following the event, whereas there was an immediate fall (RR: 0.41; 95% CI: 0.29-0.59) followed by a higher gradual increase (RR: 1.04; 95% CI: 1.02-1.06) in the rate of hospital admissions (HA) in the affected population. CONCLUSION: The results suggest that there was an increase in the utilization of public MHS by the population that suffered water supply interruption following the disaster.

The role of primary care pharmacists in the response to the Zika epidemic.

BACKGROUND: Zika virus (ZIKV) infection emerged in Brazil in 2015, leading to the declaration of a national public health emergency, mainly due to its consequences for pregnant women and newborn babies. The Zika epidemic demanded major efforts from the public health system to address the full range of disease consequences. OBJECTIVE: The objective of this study was to investigate the role of Primary Health Care pharmacists working in the city of Campo Grande in the State of Mato Grosso do Sul. METHODS: A qualitative cross-sectional interview-based study with pharmacists working in municipal Primary Health Care services was carried out to investigate knowledge about the disease and involvement in the response to the health emergency. Informed consent was obtained. After coding, the corpus underwent thematic analysis. RESULTS: The data show that few professionals had received specific training in public health. Knowledge largely encompassed disease transmission by the mosquito and collective and individual preventive measures. Findings highlight knowledge gaps relating to signs and symptoms, diagnosis, consequences of infection, and the role of epidemiological surveillance. Most professionals mentioned at least one of the recommendations on the use of medicines in symptom management protocols. The practical implications surrounding knowledge gaps and misconceptions were reflected in pharmacists´ role in response, restricted to counselling on preventive measures. Few respondents participated in institutional groups and committees or in multiprofessional teams involving case management. CONCLUSIONS: The study identified important knowledge gaps and showed that the involvement of pharmacy professionals in the response to the Zika epidemic was timid or inadequate. The results also suggest that pharmacists failed to recognize their role in interventions related to the ZIKV epidemic. Findings highlight the need to increase the involvement of primary care pharmacists in community-based actions, for communication and reduction of health risks, and emergency preparedness and response.

Dispensing and determinants of non-adherence to treatment for non complicated malaria caused by Plasmodium vivax and Plasmodium falciparum in high-risk municipalities in the Brazilian Amazon.

BACKGROUND: In Brazil, 99.7 % of malaria cases occur in the Amazon region. Although the number of cases is decreasing, the country accounted for almost 60 % of cases in the Americas Region, in 2013. Novel approaches for malaria treatment open the possibility of eliminating the disease, but suboptimal dispensing and lack of adherence influence treatment outcomes. The aim of this paper is to show the results on dispensing practices, non-adherence and determinants of non-adherence to treatment of non-complicated malaria. METHODS: The study was conducted in six high-risk municipalities with Plasmodium vivax and Plasmodium falciparum transmission in the Brazilian Amazon and based on the theoretical framework of the Mafalda Project, which included investigation of dispensing and adherence. The World Health Organization Rapid Evaluation Method has been used to estimate sample size. Individuals over 15 years of age with malaria were approached at health facilities and invited to participate through informed consent. Data was collected in chart review forms focusing on diagnosis, Plasmodium type, prescribing, and dispensing (kind, quantity, labelling and procedures). Follow-up household interviews complemented data collection at health facility. Non-adherence was measured during the implementation phase, by self-reports and pill-counts. Analysis was descriptive and statistical tests were carried out. Determinants of non-adherence and quality of dispensing were assessed according to the literature. RESULTS: The study involved 165 patients. Dispensing was done according to the national guidelines. Labelling was adequate for P. vivax but inadequate for P. falciparum medicines. Non-adherent patients were 12.1 % according to self-reports and 21.8 % according to pill-counts. Results point to greater non-adherence among all P. falciparum patients and among malaria non-naîve patients. More patients informed understanding adverse effects than 'how to use' anti-malarials. CONCLUSIONS: Non-adherent patients were mostly those with a P. falciparum diagnosis and those in their second or more malaria episode. New taxonomies and concepts on adherence stress the importance of focusing on the individual patient. Interventions targeted to and tailored for malaria patients must be addressed by health policy and implemented by managers and clinicians.

A methodological approach for the evaluation of preparedness of pharmaceutical services / Un enfoque metodológico para evaluar el estado de preparación de los servicios farmacéuticos

OBJECTIVE: The aim of this article is to provide an outcome evaluation model for preparedness of pharmaceutical services (PS) in disaster situations. METHODS: A five-step evaluation model development was conducted. The first step was a search of disaster preparedness and PS literature. The second step consisted of a description of the political and organizational aspects, external context, implementation, and performance of PS in disaster preparedness. A theoretical model on PS preparedness in disaster situations, encompassing pharmaceutical services variables and measures of preparedness, was developed as the third step. The fourth step produced a comprehensive theoretical model for evaluating PS preparedness, combining the two approaches used in steps two and three. The fifth and final step examined the development of the indicator framework. RESULTS: The results of this methodological approach are presented in the logic model of PS preparedness and the indicator framework, both of which were developed based on the disaster preparedness and PS literature and organized to provide a structured evaluation approach. CONCLUSIONS: PS was conceptualized as a program that can be evaluated by measurable effects. These effects can only be measured based on documented, on-site conditions before and after an event recognized as a disaster situation. This conceptual approach is context-modulated and therefore only applicable where the logistic cycle has been adopted as the rationale for PS.

OBJETIVO: Proporcionar un modelo de evaluación de resultados relativos al estado de preparación de los servicios farmacéuticos (SF) para situaciones de desastre. MÉTODOS: Se elaboró un modelo de evaluación en cinco pasos. El primer paso fue una búsqueda bibliográfica sobre preparativos para situaciones de desastre y SF. El segundo consistió en una descripción de los aspectos políticos y técnicos, el contexto externo, la implementación y el desempeño de los SF en la preparación para situaciones de desastre. El tercer paso fue la elaboración de un modelo teórico sobre el estado de preparación de los SF para situaciones de desastre, que comprendía variables relativas a los SF y medidas del estado de preparación. El cuarto paso consistió en la creación de un modelo teórico integral para evaluar el estado de preparación de los SF, mediante la combinación de los enfoques usados en los pasos dos y tres. El quinto y último paso fue el análisis de la elaboración del marco de indicadores. RESULTADOS: Se presentan los resultados de este enfoque metodológico en el modelo lógico del estado de preparación de los SF y el marco de indicadores, ambos elaborados con base en la bibliografía sobre preparativos para casos de desastre y SF, y organizados para poder proporcionar un método estructurado de evaluación. CONCLUSIONES: A efectos de la elaboración de este marco conceptual se consideró a los SF como un programa que podría ser evaluado a partir de sus efectos cuantificables. Estos efectos solo pueden ser medidos sobre la base de condiciones documentadas en el lugar de los hechos antes y después del evento considerado una situación de desastre. Este enfoque conceptual está modulado en función del contexto y por lo tanto se considera aplicable solamente donde se haya adoptado el ciclo logístico como fundamento de los SF.

Pharmaceutical services for endemic situations in the Brazilian Amazon: organization of services and prescribing practices for Plasmodium vivax and Plasmodium falciparum non-complicated malaria in high-risk municipalities.

BACKGROUND: In spite of the fact that pharmaceutical services are an essential component of all malaria programmes, quality of these services has been little explored in the literature. This study presents the first results of the application of an evaluation model of pharmaceutical services in high-risk municipalities of the Amazon region, focusing on indicators regarding organization of services and prescribing according to national guidelines. METHODS: A theoretical framework of pharmaceutical services for non-complicated malaria was built based on the Rapid Evaluation Method (WHO). The framework included organization of services and prescribing, among other activities. The study was carried out in 15 primary health facilities in six high-risk municipalities of the Brazilian Amazon. Malaria individuals ≥ 15 years old were approached and data was collected using specific instruments. Data was checked by independent reviewers and fed to a data bank through double-entry. Descriptive variables were analyzed. RESULTS: A copy of the official treatment guideline was found in 80% of the facilities; 67% presented an environment for receiving and prescribing patients. Re-supply of stocks followed a different timeline; no facilities adhered to forecasting methods for stock management. No shortages or expired anti-malarials were observed, but overstock was a common finding. On 86.7% of facilities, the average of good storage practices was 48%. Time between diagnosis and treatment was zero days. Of 601 patients interviewed, 453 were diagnosed for Plasmodium vivax; of these, 99.3% received indications for the first-line scheme. Different therapeutic schemes were given to Plasmodium falciparum patients. Twenty-eight (4.6%) out of 601 were prescribed regimens not listed in the national guideline. Only 5.7% individuals received a prescription or a written instruction of any kind. CONCLUSIONS: The results show that while diagnostic procedure is well established and functioning in the Brazilian malaria programme, prescribing is still an activity that is actually not performed. The absence of physicians and poor integration between malaria services and primary health services make for the lack of a prescription or written instruction for malaria patients throughout the Brazilian Amazon. This fact may lead to a great number of problems in rational use and in adherence to medication.

Proposed methodology for monitoring antiretroviral drugs price negotiations in Latin America and the Caribbean.

OBJECTIVES: The spread of HIV/AIDS challenges governments to provide antiretroviral (ARV) treatment at affordable prices, and various initiatives have been developed with that intent. In Latin America and the Caribbean, four subregional negotiations were conducted during 2002-2005 to reduce drug prices and thus broaden access to ARVs. Studies were carried out to monitor the negotiations, and the development of a monitoring methodology was recommended. The objective of the current study was to develop and describe a potential methodology for monitoring ARV price negotiations. METHODS: The study, carried out in 2006-2007, consisted of a design phase and validation phase. The design phase included an extensive literature review and development of a theoretical framework. Validation was performed using health professional consensus and pilot studies in three countries-Barbados, Honduras, and Peru-representing the Caribbean, Central American, and Andean subregions. RESULTS: The results included a detailed logic model and a 40-indicator framework. Both were tested in the field. Indicators were evaluated for feasibility, pertinence, and sensitivity, based on the outcome of the pilot study. CONCLUSIONS: This monitoring methodology is designed to help countries self-evaluate progress toward implementation of ARV price negotiations. The results of the pilot study indicate that its implementation in the field helped elucidate the ARV price negotiation process by identifying local conditions and indirectly measuring countries' negotiating capacities.

RESULTADOS: Se obtuvo un detallado modelo logístico y un marco conceptual de 40 indicadores. Ambos se probaron en el terreno. Se evaluaron la factibilidad, pertinencia y sensibilidad de los indicadores según los resultados del estudio piloto. CONCLUSIONES: Esta metodología de monitoreo se diseñó para ayudar a los países a autoevaluar sus progresos en la implementación de la negociación de precios de los ARV. Los resultados del estudio piloto indican que su implementación en el terreno ayudó a esclarecer el proceso de negociación de los precios de los ARV mediante la identificación de las condiciones locales y la medición indirecta de la capacidad de negociación de los países.

Developmental toxicity of meglumine antimoniate and transplacental transfer of antimony in the rat.

Meglumine antimoniate (MA), a pentavalent antimonial (SbV) drug, has been used for the treatment of leishmaniases for over half a century but there is almost no data on its safety and kinetics during pregnancy. This study was undertaken to investigate the developmental toxicity of MA as well as the transplacental transfer of antimony (Sb) in rats. Wistar rats (approximately 20 per group) were treated subcutaneously (s.c.) with MA (0, 75, 150, 300 mg SbV/(kg BW day)) during pregnancy (days 1-20). An untreated control group was evaluated as well. Caesarean sections were performed on day 21 and implantations, living and dead fetuses, and resorptions were recorded. Fetuses were weighed and fixed in Bouin's solution and one-third of each litter was examined for soft-tissue anomalies. The remaining fetuses were cleared and stained with Alizarin red S for skeleton evaluation. No adverse effect of MA on the mothers was noted at any dose level. No embryotoxicity was observed at the lowest dose but, at the highest dose, MA increased embryolethality, reduced fetal weight and augmented the occurrence of some soft-tissue and skeleton variations. Therefore, the no-observed-adverse-effect level for MA-induced embryotoxicity was 75 mg SbV/(kg BW day). In a separate group of rats treated with 300 mg SbV/(kg BW day) s.c. during whole pregnancy, blood (0.2 mL) was taken from the tail vein 1, 2, 4, 6, 12 and 24 h after treatment on day 1 and thereafter every other day immediately before drug injection. Blood was also taken from fetuses removed on day 21, 24h after the last injection of MA. Blood levels of Sb were determined by ICP-MS and results showed that most of administered Sb was eliminated rapidly (in less than 6 h), but nadir blood concentrations increased gradually during treatment from 1 to 2 microg/g, 24h after the first dose, up to approximately 38 microg/g after the 20th dose. Levels of Sb in fetal blood were as high as 10-15 microg/g, i.e. approximately 30% their mothers' nadir levels near term. These findings indicated that repeated administration of MA during gestation led to an accumulation of Sb in mothers and fetuses.
